FOLDING BOX.

SPECIFICATION forming part of Letters Patent No. 688,313, dated December10, 1901.

Application filed April 5, 1901. 6 i533- (No mo l-1 To all whom it mayconcern:

Be it known that I, CHARLES F. KELLER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Folding Box, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof. My invention relates to improvements in folding boxes;and it consists in the novel combination and arrangement of parts, aswill be view of the blank which forms the box.

'vention, showing the box in a folded posi- -.tion; and Fig. isavertical section ofa porhereinafter more particularly described andclaimed.

In the drawings, Figure '1 is a perspective view of a folding boxconstructed according to my invention with one of the sides thereof,

Fig. 2 is a plan view of Fig. 3 is plan Fig. 4 is a plan view of amodification of my inin an open position. the box in'a folded position.

tion of the box.

' The object of my invention is to construct a simple, practical, anddurable folding box more especially constructed for millinery purposes,the same being constructed practically of one piece of material and whenfolded in the manner hereinafter described to form a box is composed ofafiat bottom and top, the latter being of smaller dimensions than theformer, whereby the sides are arranged at an incline, forming what maybe termed a truss-framed folding box which provides strength andsimplicity, and, further,one that is more desirable in appearance.

Referring to the drawings, 1 represents the blank from which the box ismade and is composed of a central rectangular portion 2, which forms thebottom for the box, the material being creased, as shown'by dotted lines3, and forming a continuation of said bottom and arranged diametricallyopposite one another are two extensions 4, the latter being creased atan angle tothe opposite edges of the same, as shown by dotted lines 6,pro ducing side wings 7, said wings being righttriangular in shape, withthe apex at the bottom, whereby the blank may be cut with less expenseand the formation of slits, &c., at the juncture of the bottom of theextensions 4 with the bottom 2 prevented without loss of strength. Saidwings are bent at right angles to said extensions when the box is set upfor use, thereby strengthening 'thesame, the upper edges of said wingsproducing supporting-ledges 8, with which the tongues of the remainingextensions cooperate. Forming a continuation of the extensions 4 aretongues 9, the parts being bent on creases, (shown by dotted lines 10,)said tongues-being each provided with hooks 11, located at the ends ofthe same and made from the material. of which'they form a part, wherebywhen ,said hooks are united in the manner shown in Fig. 1 two of thesides of the box areformed and also the top. The extensions 12, formingthe remaining side walls .for the box, are each creased adjacent totheir ends, as shown by dotted lines 13, forming tongues 14, which arepassed under the top previously described, and over the upper ledges 8of the wings 7, the opposite edges of the said extensions 12 beinginclined to conform to the shape orincline of the opposite side walls ofthe box. Secured to the extensions 12 are strings or cords 15, which aretied together in the usual manner over the top of the box after thelatter is formed, whereby all of the parts are rigidly held together inrespect to one another. 7

When it is desired to form the box, the blank 1 is unfolded in themanner shown in Fig. 3 and the hat or other article laid on the bottom2, after which the extensions 4 are elevated'and the hooks 11 united,thereby forming a bottom, two side walls, and the top. The otherextensions are then elevated, forming the remaining side walls, and thetongues 9 forced under the top and over the ledges 8 of the wings 7,after which the cords 15 are tied and the article inclosed. From theforegoing description it will be seen that the top of the box thusformed is supported by the entire upper creased edges'of the extensions12, the tongues forming the terminal ends of the latter operating tostrengthen said supporting creased edges, it being further observed thatafter the tongues are inserted between the top and upper edges of thewings 7 the latter assume an inclined position in respect to said top,as shown in Fig. 5, temporarily holding the various parts of the box ina rigid position before the strings are tied. In view of these facts itwill be readily understood that when folding or unfolding the box thereis no requirement of the making of a diificult insertion of tongues, thesecuring of the extensions having the locking-tongues being readilyaccomplished, after which it is necessary only to pass the tongues 14between the top and the upper edge 8 of the wings 7, which can bereadily done without the requirement of the manipulation of the tongues,as is the case where a paper tongue is to be inserted within a slit.Furthermore, as the tongues 14 are not adapted to have any interlockingconnection, being, in fact, out of contact with each other when inposition, this placing of the tongues in position can be quicklyaccomplished, and owing to the strings being attached to the extensions12 instead of to the tongues 14: the box is held in rigid positionwithout the requirement of an interlocking connection between thetongues 14:.

In Fig. 4 I have shown a modification of my invention, the onlydifierence in construction being the formation of the tongues 9', whichform the top of the box, a tongue 16 being employed of suflicient lengthto remain in a slot 17, formed in the opposite tongue 9,

,whereby the folding of the box when not in use is somewhat diiferentand the tongues 9 always connected. By elevating the extensions 4 andforcing the same toward one-another the bottom, two side walls, and topare formed in practically one operation.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A blank for a folding box having a central portion adapted to form abottom, extensions formed on each of the four'sides of said bottomportion, two of said extensions having sides in alinement with thecrease of the bottom, the remaining extensions having inclined sides,non-adjoining extensions having the same configuration, portions of theextensions having the alined sides being adapted to be folded to formwings, tongues formed on said winged extensions and provided with meansfor securing them together to form a-top, and tongues formed on theremaining extensions, said latter tongues being of a combined lengthless than the distance across the top of the box, substantially asdescribed.

2. A folding box formed of a single piece of material, having a bottom,inclined sides, a top formed by the opposite ends of two of said sides,the ends of the remaining sides being insertible below said top out ofcontact with each other, said ends being supported against collapsinginwardly by wings righttriangular in shape with the apex at the bottomof the box, and strings attached to the sides having thenon-contacting-ends or tongues and adapted to be tied over the said top.

3. A folding box comprising a bottom, extensions forming a continuationof the same and arranged at an incline,forming side walls, wingsright-triangular in shape with the apex at the bottom of the box,located on the opposite sides of two of said extensions, the upper edgesof which form supporting-ledges, tongues forming the ends of thelast-named extensions, producing a top, means for securing said tonguestogether, tongues forming the ends of the remaining extensions, andadapted to be located under the top out of contact with each other andsupported by the ledges of the wings, and strings attached to last-namedextensions, and adapted to be tied together over said box, whereby thetop of the box is of smaller dimensions than the bottom, as and for thepurpose described.

4. A folding box comprising a bottom, extensions forming a continuationof the same forming side walls, wings right-triangular in shape withapex at the bottom of the box,located on the opposite sides of twoofsaid extensions, the upper edges of which'form supporting-ledges,tongues forming the-ends of the last-named extensions producing acomplete closed top, means for securing said tongues together, tonguesforming the ends of the remaining extensions and adapted to be locatedunder the top thus formed and cooperate with the upper supporting-ledgesof the wings, whereby the creasededges formed by the last-named tongueswill support the top, and strings attached to the latter extension andadapted to be passed over said creased edges and tied together over thetop, substantially as described.

5. A folding box comprising a bottom, extensions forming a continuationof the same forming side walls, wings right-triangular in shape with theapex at the bottom of the box, located on the opposite sides of two ofsaid extensions,the upperedges of which form supporting-ledges, tonguesforming the ends of the last-named extensions, said tongues be= ingnormally held in interlocking relation whether the box be folded orunfolded, said tongues forming a complete top, tongues forming the endsof the remaining extensions and adapted to be located under the top thusformed and cooperate with the upper supporting-ledges of the wings,whereby the creased edges formed by the last-named tongues will supportthe top, and strings attached to the latter extension and adapted to bepassed over said creased edges and tied togetherover the top,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
